IMPROVEMENT IN CARRIAGE-AXLES.

To all whom it may concern:

Be it. known that I, J O-HN GRABAGH, of Clyde, in the county of Sandusky, and .State of Ohio, have inventeda new and improved Axle for Vehicles; and I do hereby declare that the following is a full, clear, andwhich the axle will be kept greased in a uniform inanner.

The invention consists in forming an oil-reservoir with an adjustable slide on the shank of the spindle, and a spiral groove on the body of the spindle, all as hereinafter more fullydeseribed.

A represents the spindle.

a, the shank of the spindle.

Y b, the shoulder.

c, the oil-reservoir, arranged upon the shank a. It is calculated to hold sniiioient oil' to run a wagon fifteen or twenty days.

The lid ll, to this reservoir, is held closed by means of a spring-catch, c, which is attached to the side of" the reservoir,-and which is spmmg back to take the lid off.

f is a screw, working through the back end of the reservoir, and swivelled to a regulator-plate B, which works in the reservoir, and'hy which the oil is admitted to or shut off from the spindle.

The spindle is attached to a wooden or other axle of a wagon, in the same manner as an ordinary pipebox. Channels 9 are cut into the spindle to form one 'or more continuous spiral grooves fromthe shoulder b,

The Schedule referred to in these Iietters Patent and making part of the same.

through which the oil is first admitted, to the end of the spindle or screw 71, where the oil will drop off if used too fast, thereby preventing poor oil from getting gummy, which it would do if not-allowed to pass off. The oil will work forward only by the forward revolution of the wheel.

' A nut, 'i, is screwed upon the end h of the spindle, when the wheel is placed on the axle, to hold it in its place, or taken off when required.

0 is the boxing or thirnble, which is fitted to the inside ofthe hub, and differing onlyfrom the common thimble by being plain all along its whole length, while the common thiinble has a sort of recess on the middle, and works not so close on the middle of the-spindle as on the ends. I

The cars j are to hold it more firm to the hub,

The regulator-plate B is fitted into the oil-reservoir, and is worked by the screw 1, so as to bring its upright end It nearer to or further away from the aperture through the shoulder b, which forms the inner end of the reservoir.

The spindles will be right aml left for the opposite wheels, fig. 1- showing a right one; the left will differ only by having the channel g, and thread on screw 7:, and nut, cut in the opposite direction, and the spring 0 on the opposite side of the oil-reservoir.

The whole device will be of cast-iron of the best quality, except the spring 0, which will be of springsteel, and the screw f, which may be inadeof steel or rod-iron.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The spindle A,pr ovided with the oil-reservoir c behind its shoulder 11, with the adjustable slide B in'the reservoir, and with the spiral groove or grooves g in front of the shoulder, all arranged, combined, and operating substantially as herein shown and described.
